PAPER-BOX MACHINE.

SPECIFICATION forming part of Letters Patent No. 721,557, dated.February 24, 1903.

Application filed July 28, 1902.

To all 1.071 01% it may concern:

Be it known that I, CHAUNOE'Y W.GAY, a citizen of the United States ofAmerica, and a resident of West Springfield, in the county of I-Iampdenand State of Massachusetts, have invented certain new and useful Improvements in Paper-Box Machines, of which the following is a full,clear,andexactdescription.

This invention relates to machines for mak ing rectangular tubularboxes, lined with paraffined paper or. similar material, so as to renderthe receptacle moisture-proof; and my invention has for one of itsobjects the provision of a machine whereby the several box forming andlining operations are systematically carried out.

My invention has, furthermore, for its object the provision of meanswhereby suitable reading matter, 850., may be printed on the outersurface of the box-blank and the combination therewith of a web ofpaper, which is fed through the machine and is cut into lengthscorresponding to the boxes, so as to prevent offset of the fresh ink,this paper being interposed between the box-blanks and separatedsimultaneously therewith.

Further objects of my invention may be found in the improvedconstruction and organization of some of the cooperating ele-' ments, aswill be hereinafter described and as is illustrated in the accompanyingdrawings, in which similar characters denote similar parts, and in whichFigures 1 and 2 together represent a longitudinal section of my improvedmachine. Fig. 3 shows a cross-section on line 3 3 of Fig. 1. Fig. 4 is aperspective view of the front end of the machine, illustrating themanner in which the paper from which the boxes are to be formed isentered and fed into the machine. Fig. 5 is a cross-section on line 5 5of Fig. 1. Fig. 6 illustrates a plan View, of a strip of paper, showingthe manner in which it is scored and cut,the fine single linesrepresenting the scores and the heavier double lines indicating the outor slotted portion. Fig. 7 is a cross-section on line 7 7 of Fig. 1.Fig. 8

2. Fig. 14 is a perspective view of the blankfiattening devicepreparatory to subjecting the blank to the compressing members wherebythe gumme'd loose ends of the blank are caused to adhere to each other;and Fig. 15

is a perspective showing the tensioning de- .vioe for the blan k-stripand the transfer-guide for supporting said strip during its passagebetween the printing-couples.

The present machine is an improvement on the box-machine shown anddescribed in Letters Patent No. 695,301, granted to O.W. Gay, and alsoon that shown in Patent No. 695,369, granted to A. Birnie and O. W. Gay,both patents bearing date of March 11, 1902, and inasmuch as theparticular box which is to be formed by my improved machine has beenfully described in the patents above named I do not deem it necessary todescribe the general construction of the machine.

In the drawings, 20 represents a suitable framework supporting at oneend a supplyweb roll 21 of cardboard or similar material from which thebody of the box is to be made.

Supported by standards 22 near the initial end of the machine, butforward of the support for the supply-web roll, are a pair of arms 23,which are adjustable crosswise of the machine on a stationary rod 24 andmay be held fixedin any of their more or less separated positions and inrearward extension from said supporting-rod by the confiningscrews shownin Figs. 1 and 4. Pivotallysupported at the extremities of said arms 23are guides 25, preferably trough-shaped in cross-section, butessentially comprising separated members one above the other toengageabove andbelow the running web, at the marginal portions thereof, forguiding the same over a tension-rod 26 and under another tension-rod 27to a running-course'over a tension-roll 28, which is supported inadjustable journals within the uprights 22. Directly under the saidtension-roll, parallel therewith, are the pair of slitting and scoringrolls 28 and 29, said tension-roll 28' being so close to the peripheryof one of the rolls of said pair 28 29 as to bind the supply-web, whichpasses around the roll 28 and between it and the one of such pair ofrolls before the web has a half-encircling disposition around the roll28 in its forward passage through and between and subject to theslitting and scoring action of the rolls 2S and 29, and such pair ofslitting and creasing rolls 28 and 29, it will be understood, mayadvantageously be of substantially the same form and construction asthose shown and described in the aforementioned patent. It will beparticularly perceived that the roll 28' has its location axiallyremoved from the direct line extended from the periphery of theweb-supply roll to the line of the meeting peripheral portions of thesaid scoring and sli ting rolls 28 and 29, whereby the course of the webrunning from the supply-roll to and between and subject to the scoringand slitting action of the said pair of rolls 28 29 must be one almostentirely encircling the top roll 28' and half on circling the roll 28 inor almost in contact against and under the tension-roll, so that the webis absolutely held firmly and without any possibility of slipping orbecoming slackeued at the place or line in the machine at which thecarton-producing operations may be considered as having their beginning,and the web will be forwardly drawn, against the resistance of thereliable character as insured by the arrangement above described andexplained, by the draft action of the cylinders or rolls 53 to 60, oneor more, as provision thereof is made, which latter-mentioned draftmechanism, as hereinafter pointed out, is comprised in the printing andcutting-off arrangements.

In order to efficiently friction the web-roll 21 while the web is beingwithdrawn therefrom, flat rearward extensions of the guidestrips 25 arepreferably arranged to rest upon the web-roll, a weight or weights oftransversely-extended bar form, such as shown at 30, being provided andvertically guided between uprights 31, such weight bar or bars havingbearing on the free extremities of the guide-strips. After the web haspassed the scoring and slitting rolls a narrow strip of paste or gum maybe supplied thereto by the gumming mechanism, indicated herein by 32.

Journaled in uprights 33 is a web-roll 34, of lining-paper, which maybeof any suitable species and which may be frictioned by a strap 35,pulled into contact with said roll by a weight 36, as shown in Fig. 1.The liningweb L is'carried over a roller 37, adjacent to a roller 38 andcooperative therewith, for bringing the lining-web L and the main web Minto close contact with eachother, but in such a manner that the edgesof the webs overlap each other, substantially as shown in Fig.

5, so that the paste which is laid upon the edge of the main web M willremain untouched for the time being. Both webs M and L are now conductedinto a trough 40, substantially V-shaped in cross-section, the websbeing folded on the longitudinal central score-line and substantially asillustrated in Figs. 7 and 8, and in order to insure the webs beingfolded in the proper manner means are provided whereby the centralportion of the webs is drawn or forced into the bottom of the trough40," these means consisting substantially of a creaser-finger 4.1. (SeeFigs. 8 and 9.) From this folded trough 40 the webs are conducted toanother trough 42, the sides of which are more closely drawn together atthe top, one of said sides being, furthermore, bent over, substantiallyas shown in Fig. 10,whereby the fiat end of the box-blank is folded onits scoreline preparatory to being brought into contact with the pastedside thereof.-

Since the upper end of the box-blank duringits passage from the trough40 to the trough 42 tends to bend the flap inward without creasing thesame, means are provided whereby the web is maintained in spreadcondition during the formation of the bottom fold, these meansconsisting substantially of a top-fold finger 43, (see Fig. 9,) overwhich the flap will be bent Without danger of striking the gummed sideof the box.

After the flap has been primarily bent in the manner above described itis still further bent over or creased into the required condition by atop-fold former, such as 44, clearly shown in Figs. 1 and 10. The web isnow passed to a device whereby the gummed blanki'lap is caused tocontact with the plain blankside, so as to deposit a part of thegum-supply thereon, this device being preferably in the nature of a rod45, bent at its ends and secured to a vertically-disposed shaft 46,which may be rotated until the required degree of bend, and at the sametime tension, will have been obtained, the web passing between the shaft46 and the rod 45, so that according to the position of the latterrelative to the former the web will be in more or less tight contactwith the rod, thus tensioning the web and at the same time folding theupper flap of the same.

From the above it will be understood tha in reality a part of thegum-supply on the edge of the blank-web will be deposited upon the flapside.

Now it has been found in practice that it is of material benefit in theoperation of forming a box of this character that the flap end shall beagain separated from the main web after a part of the gum-supply hasbeen de posited thereon, this action resulting in permitting the gum toset to a greater or less extent and according to the duration of timewith which the gum is exposed to the air.

Hence the web is now ready to be collapsed by distending the sidesthereof, which action will result in bringing the vertically-oppositecreases or corners of the box-blank toward each other and in thedirection shown by arrows in Fig. 13. The device whereby this collapsingaction is effected is clearly shown in Fig. 14:, in which 47 denotes apair of horizontally-disposed spreaders, which constitute supports forthe blank-corners and which may be supported'in any suitable manneras,for instance, by wires 48, adj ustably supported in uprights 49.

In order to insure the corners beingfully creased at their respectivescore-lines, cornerfiatteners, such as 50, may be provided forcooperation with the flatteners 47 and may be made subject to suitableadjustment relative thereto in any desired manner.

Means are provided for supporting the gum flap in proper positionrelative to the blank-body during the collapsing thereof, these meansbeing herein shown as a wire 51, disposed below the flap'portion of theblank, as shown in Fig. 14, so that as the web is gradually more andmore collapsed the flap will be prevented from striking the lowerportion with its edge, and, furthermore, will come in proper position torecontact with the gum of the blank-body, the web being drawn through atension, or what might be more properly termed a contacting, device 52,the construction of which is substantially similar to the tension device44 and 45, above described, and which is, however, horizontally disposedinstead of vertically. The boxblank is now practically complete and in ahorizontal plane, so that it may now be passed to a mechanism wherebythe collapsed blankstrip may be firmly compressed. This mechanismcomprises in the present instance a pair of coacting presser-rolls 53and 54, disposed at opposite sides of the web, respectively, and servingto force the gummed surfaces together, thus forming what may now betermed a blank-strip, which may then be conducted to a printingmechanism comprising a printing-roller and an impressionroller 55 and56, respectively, whereby any suitable reading matter may be printedupon the outside of the blank.

While the printing mechanism just described is operative only on theunder side of a blank, (see Fig. 2,) similar printing-couples may bedisposed above the blank-strip, so as to imprint the outer side of theblank-strip as desired, each of the impression-rollers being preferablycovered with rubber, so that any inequality of thickness of theblank-strip will not be detrimental to the production of a uniform andclear print.

In Fig. 2 I have illustrated printing-cylinders 57 and 58 for printingthe upper surface of the blank-strip, while impression-rollers 58 and 60are disposed below the said strip, and means are provided whereby theblank-strip may be supported and guided between the several sets ofrollers, these means being connection. with the main and lining webs, soas to prevent oifset of the .fresh ink, and in Fig. 2 I have illustrateda roll of paper 0, which is laid over the impression-roll 58 and fromthis point onward movesin unison with the blank-strip, so that the freshink deposited by the roller 55 on the under side of said strip will notbe deposited on either of the impression-rollers 58 or 60, abovementioned. This offset-web accompanies the blank-strip through a cuttingdevice 61, whereby the blank-strip is cut into box lengths and which ispreferably organized in connection with the last set of printing-couples59 and 60, above referred to. As the blank-strip is cut to form boxlengths the offset paper is cut off simultaneously therewith and will bedeposited between the cut box-blanks as the latter are discharged fromthe machine. The opposite par- 1 allel cross-sectionally trough-shapedguidestrips pivotally hung to the extremities of the bracket-like arms23 have provided at the extremities thereof, which are in bearing on andadjacent the top of the web or roll 21, and

which extremities, as indicated inFig. 1, are each in the form of asingle strip corresponding to the upper leaf or section of theguidestrip, such strip not being continued in the full trough formentirely to the end, the depending side plates or cheek members 25 whichextend down coincident with the planes of the ends of the supply-rolland have restraining bearings thereagainst, so that the guide-strips canhave no tendency to any transverse or twisting displacement, but, on theother hand, so that the strip will at all times be constrained in itsrunning course to move accurately and strictly at right angles to theaxis of the aforementioned tension-roll 28, and the web being truly andsquarely brought to this tension-roll is by the co6peration which thisroll has not only with the guiding and squaring device which has beenparticularly described, but with the scoring and slitting rolls 28 and29, which are next to and directly under said tension-roll 28,alwayscaused to have its forward feeding movement in positive uniformity withthe draft or feeding of and printing contact on the completed I claim asnew, and desire to secure by Letters Patent, is i 1.
